WALTER HUNT, or NEW YORK, N. Y.,

ASSIGNOR TO GEO. A. ARROWSMITH.

LOADED BALL Speci ication forming part of Letters Patent No. 5,701, dated August 10, 1848.

To all 'whom it may concern Be it known that I, \VALTER HUNT, of the city, county, and State of New York, have invented a new and useful Improvement in the Construction of a Metallic Cartridge, made entire with the ball,1'or fire-arms, which I term a rocket-ball, and I do hereby declare that 'of the same, showing the internal structure of thccap A, cavity 1) in the cartridge B, and itsjunction with the ball C.

Thedissectcd longitudinal cut-section, Fig. 3, shows the cap A separated from the flange or neck formed by the shoulder, at the dotted line E, upon'therear end of B.

Fig. 4 is an end or face View of A, which in form resembles the Chinese gong, with a ccn tral perforation, F, in its discous head, which is the point of ignition from the priming. Over this perforation, upon the inside face of said cap, is placed a thin water-proof tissue or seal. (See Fig. 2, at the dotted line G, and This seal may be made of any thin material through which the fire from the priming may penetrate, and which will at the same time secure the powder in the cartridge from escape or accidental injury.

This ball and thimble should be formed in molds by pressure. The powder being well packed in the cavity 1), the cap A, lined with the seal G, being fixed upon the flange, and pressed up to the shoulder E, should then be subjected to a second pressure, in order to fix the cap firmly and produce a uniformity in the size of the cartridges.

It will be readily perceived that this plan of a combined ball and cartridge is well adapted to firearms made to be eharged'at the breech, from the fact that in firing this ball the cap A is left in the breech, withsits head or disk pressed firmly against the breech-plug,'and its rim or flange forced outward against the inner periphery of the calibcrof the barrel, forming an air-tight stopper, which effectually prevents all backward escape of the powder, notwithstanding the breech-plug may be loosely fitted in the breech of the barrel behind the charge, which must necessarily be the case in all reciprocating breech-pins in order to prevent their binding from heat, deposits, &c., in rapid firing. It is also obvious that, in'guns made with piston breech-pins, the cap A in my plan would be carried out forward of each succeeding ball, operating as an efiectua'il wiper to the barrel at each discharge of .the piece.

What I claim in the abovedescribed invention, and desire to secure by Letters Patent, 1s-

The construction of a ball for firearms, with a cavity to contain the charge ofpowder for propelling said ball, in which cavity the powder is secured by means of a cap inclosing the back end of the same, substantially as described.

WALTER HUNT.
